This adds support for Innolux LS075AT011 7.5" 1200x900 panel.
The panel is not a regular LCD with RGB pixels. Its pixels are just of
one color, organized like this:
g b r
b r g . . .
r g b
.
.
.
It's controlled by the Himax HX8837, which takes the RGB data, optionally
dithers the colors by swizzling and drives the panel. I couldn't determine
what the bus_format is. There's six data pins marked FD00, FD01, FD10,
FD11, FD20 and FD21.
There's no public data sheet. The clock is taken from the OLPC's
OpenFirmware, I don't know why precisely that number. It seems to work.
